HENRY It. PARROTT, OF DAYTON, OHIO.

IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 197,401, dated November20, 1877 application led August 17, 1877 To all whom it may concern:

Be it known that I, HENRY It. PARROTT,

lower rail of the sash; and my improvementsconsist in the novelconstruction and arrangement of the button and of the operating devices,whereby both simplicity and durability are combined, all as will behereinafter more fully set forth and claimed.

In the accompanying drawings, Figure 1 represents the corner of a windowsash and frame, with a portion cut away to show the application of myimproved sash-supporter. Fig. 2 is a front elevation of the escutcheonand knob or button. Fig. 3 is a side elevation of the same as applied tothe lower rail of the sash. Fig. 4 represents, in side elevation, theposition of the button in the act of raisin g the sash. Y About thecenter of the front face of the lower rail A of the sash I form a recessor mortise to accommodate snugly the case or shell B, which may be ofany suitable shape or construction. In this shell, and journaled in itstwo faces in the ordinary way, is a central hub, C, with a squaresocket, into which the shank of the knob or button D flts, and from thehub extend two segmental arms, a, with cam-faces, as represented.Encompassing the hub and arms a is a heart-shaped collar, E, of theshape shown.

F represents the bolt conned in a mortise cut from the edge of the sashinto the recess occupied by the case B. This bolt is of the shape shown,and has upon it an enlarged portion, b, that forms a shoulder for oneend of an encompassing spiral spring, d, whose opposite sideabuts-against the edge of the case or against the separate flat piece ofmetal c, mortised into the rail, asindicated in Fig. l. The inner endofthe bolt passes through the piece c and the edge of the case B, and isscrewed or otherwise fastened in the head of the collar E. t Asindicated in Fig. 1, this head rests in aslot in the bottom of the case,though such arrangement is immaterial. The bolt is held thrust into itsseat in the frame by the spring d, and it is drawn, when desired toraise the sash, by turning the button D either to the right or left.

The escutcheon G, Fig. I, forms an ornamental cover for the case B, andserves as a bearing for the shank of the button.

It is to be noted that when the sash is locked the button stands in avertical position, as indicated in Figs. 2 and 3; and to draw the boltit is only necessary to turn the button either way until it .lieshorizontally, as in Fig. 4, when either one of the arms a, actingagainst the collar, will withdraw the bolt. In this last position thebutton forms a very convenient device for raising the window-sash.

This novel construction and arrangement is particularly useful oncar-windows, and enables a person to unbolt and raise a window with onehand and at the same operation.

The shape of the end of the bolt is immaterial, as also the constructionof the device in the frame for supporting it.

I am aware that it is not new to operate a locking-bolt, such as hereinshown, for window-sashes, by a button centrally located upon the lowerrail of the sash; and consequently I make no claim to the principleinvolved.

What I claim as new, and desire to secure.

by Letters Patent, is as follows:

1. In a lock for window-sashes, the collar E, to which is connected thebolt F, operated by the hub C and radial arms a, whereby, upon turningthe button D in either direction, the bolt is Withdrawn, substantiallyas set forth.

2. The arrangement of the button D, in combination with the rail of awindow-sasl1,where by, when turned either way to withdraw the bolt, itforms a flat bearing for raising the sash, substantially as shown.

3. The herein-described device for locking and elevating a window-sash,consisting ofthe case B, bolt F, with its spring d, collar E, hub O,with its curved arms a, escutcheon G, and button D, the whole beingconstructed and applied in the manner and for the purpose specified. v

'Witness my hand this 13th day of August, A. D. 187 7 HNRY It. PARROTT.
